据推测，变道车辆会在车流中产生空隙，而这些空隙会减少流量。这一机制被描述为一个精确跟踪车道变更者的模型，作为被赋予真实机械属性的粒子。该模型有四个易于测量的参数，无需重新校准就能再现两个以前被认为是无关的瓶颈现象：(I)当拥堵开始时，高速公路瓶颈的排污率下降；(Ii)移动瓶颈的速度与其通行能力之间的关系。(C)2005爱思唯尔有限公司。保留所有权利。
It is postulated that lane-changing vehicles create voids in traffic streams, and that these voids reduce flow. This mechanism is described with a model that tracks lane changers precisely, as particles endowed with realistic mechanical properties. The model has four easy-to-measure parameters and reproduces without re-calibration two bottleneck phenomena previously thought to be unrelated: (i) the drop in the discharge rate of freeway bottlenecks when congestion begins, and (ii) the relation between the speed of a moving bottleneck and its capacity.
